IMPROVEMENT IN BASE-BURNING STOVES.

Specification forming part of Letters Patent No. 133,608, dated December 3, 1872.

To all whom it may concern:

Be it known that I, CARL OLOF WESTLAND, of Troy, in the countyof Rensselaer and State of New York, have invented an Improved Stove, of which the following is a specification The present invention relates to an improvement in what is known as base-burning stoves;

and the particular improvements are fully set forth in the following description.

In the drawing, Figure 1, Sheet 1, is a vertical sectional elevation of my improved stove; Fig. 2, Sheet 2, a perspective view of the upper part of the fire-box and air-flue; Fig. 3, a sectional elevation of a part of the stove taken transversely to the same part in Fig. 1, Sheet 1; Fig. 4, Sheet 2, a horizontal section of the stove, looking down upon the grate.

The nature of the present invention consists in the novel construction of the fire-box, and its arrangement with the other parts of the stove, as the whole is hereinafter fully described and shown.

A represents the base of the stove, which is provided with an opening, 2, Fig. 1, Sheet 1, for the purpose of allowing an upward current of cold air, and also provided with a dumpinggrate, K L, Figs. 2 and 4, which is hung to the upper part of the base A, by means of an ordinary journal, in the usual manner. This grate is held in place, when it is to sustain coal, by means of a laterally-sliding stop, B, which operates in a slot, 5, Fig. 4, made in the base A near its top, at such a height as will allow the stop to pass under the grate, as shown at Fig. 1, Sheet 1, the stop catching under one bar of the grate, as shown at Fig. 1, Sheet 1. This is a simple yet effectual means used to prevent the grate from accidentally dumping when supplying the magazine with fuel, or from other causes. The firebox E is formed in a peculiar manner, and it is surrounded by a double wall, J B, to prevent the escape of heat and to provide proper air-chambers; and it is cast in a separate piece from the other parts of thestove, as shown at Fig. 2, Sheet 2, as it is removed;

and it is provided with a short upwardly-prm jeeting pipe, at, which communicates with an opening, 2, in the base of the stove, and a hotair chamber, G, surrounding the magazine G,

the hot air therefrom passing out at the top of the stove through a perforated plate, I). The darts 3 c 0 show the direction of the air in its passage. This current of air keeps the magazine G cool by filling the chamberbetween it and the cylindrical plate H. At the top of the magazine G there is an escape for gas through the duct P to the flue M. The top part of the fire-box E is provided with openings S for the downward passage of the products of combustion, and said openings S are provided with upwardly-projecting prongs F to prevent coal from falling into them. The space I between the wall of the fire-pot E and the diving-ii ues J forms a continuous annular ai'r chamber around the fire-pot. Said chamber communicates with the open air through one or more orifices, 2, at its bottom, and it communicates with the chamber around the reservoir G by the pipes at M N, by means of which a supply of air is conducted to the chamber around the magazine, when required, in large heating stoves. v

The products of combustion, after passing down through the openings S, pass nearly horizontally around the stove, between the plates J B, and then enter a flue, I D, and pass out at M, Fig. '1, in the direction indicated by darts d.

The upper part of the stove is constructed in the usual manner, and it is connected with the magazine G, plate or section E, and flue D at S. f is the slide which covers the opening 7 in which coal is put, the slide being moved back and forth by any suitable knob or projection, Q. The section G is provided with a downward-projecting funnelshaped part, 1), at the bottom of which is a flange or ring, 0, which supports the magazine G, the lower end resting on it. The lower edge of the section 0 rests on the top of B, and the section H on the top of G. The several parts maybe fastened together by bolts and nuts in the usual manner of securing stove-plates.

To dump the grate K L, move the slide B laterally in the slot 5, as indicated by dotted lines 6.

I claim as new and desire to secure by Letters Patent-=- 1. The fire-box E, combined with an annular air-space, I, surrounding said firebox and located between it and the divingfiu e cham- G, and section 0 D, flange 0, without or with the1 pipes N M, as and for the purpose specifie 3. The combination of the air-space or jacket I surrounding the fire-box E with the airchamber G surrounding the magazine G, said air-chambers being provided with communicatin g passages a M N and suitable openings to the surrounding air at bottom and top.
